Dye free prescription medication

This is a petition for people to sign who have or know of people who are not able to have any dyes in products that they use due to the effects that it has on them. My son is one of them he was on a prescription medication that had red dye in it and it altered his personality and now will take 2 -3 days to let the dye work out of his system. P Lease sign this petition so that we can get the pharmaceutical company's to start working on making DYE FREE prescription medications for us !!!!!!!!!!!!!!!
